Fox Shox Polymer DU Bushing Reducer Kit

New Polymer DU Mounting hardware from Fox has lower friction and helps to deliver better small bump compliance than the previous DU bushings. In addition the polymer mounting bushings have better longevity and are easier to install.

Lower friction for Increased Small Bump Compliance

Increased Longevity

Easier to Install

Please Note: This bushing reducer kit is enough to replace the bushings on one eyelet of your rear shock; if replaceing the bushings on both eyelets you need to purchase a quantity of 2 kits. Also note that many bikes use different sized bushings for each eyelet, so please verify which size you need before ordering.

If it's time to replace your DU bushing I would seriously consider this upgrade.

It's a pretty straight forward upgrade and goes a lot easier if you have the tool to press out the old bushings which is why I say "difficult to install".

But you only need to press them out once - going forward you won't need to worry about it again!

If you don't have the tool you *can* use a 6mm or 8mm hex wrench to press it out or just pay your LBS a small fee to have them press it out. If you're lucky they may not charge you anything since it only takes about 5 minutes.

If your stock DU bushings are good then I would recommend just staying with them until they need replacing.

After 2 yrs of modest riding on my Tallboy C and Fox RP2, the lower DU was well past done, evidenced by a pronounced creak of metal on metal and a lot of vertical play. Most reviews said these had less friction than DU (lubricant-coated-metal) bushings so I was cautiously optimistic that it would improve small bump compliance. Well I have to say these have improved everything, small bump, large bump, and most of all rebound. The simple rebound damping on my RP2 is pretty underwhelming, and either bucks you at slow speeds or doesn't recover fast enough at high speeds, usually both, somehow these bushings have helped in both departments. They have also been silent since day 1 and were easy to install. I did spray some dry teflon lube (Remington drylube) on the inner surface just to help them settle in.

Much better then the DU Bushings. The real test will be on a Yeti ASR5 which goes through the DU bushings like crazy. These are suppose to be more durable but time will tell. Hopefully the price will come down on these I prefer them over the DU bushings for their ease of removal and installation but they are about 10x the price of the standard bushings.

Twice during the last year the upper steel DU bushing on my Fox 23 rear shock developed play noticeable when lifting up the bike by the seat. This replacement should last much longer than the steel DU bushing. Best of all, it is super easy to replace once you have the steel bushing removed. The video instructions on the page below are very helpful.

These bushings work on the Cane Creen DBInline Shocks. BUT, I had to press out the brass insert before they would fit. Its not incredibly easy if you dont have the right tool but I was able to get them out with a correct diameter socket and c-clamp.

These are cheaper and easy to get than the Cane Creek bushings, so I prefer to use them!

Well I made sure to order the correct length bushing, unfortunately Jenson had a box that they had labeled wrong because the product number on their label did not however match the fox product number on the bag. I waited almost a week of riding for them to arrive so of course I didn't even think of returning to wait for the right length so I sanded the 4 hundredths of an inch down using 80 grit then finishing with 120 grit. All in all they weren't close to perfect but they worked... For a lil while! in the mean time I contacted Jenson, easy to work with... Just took 6 or more weeks and 3 phone calls before I received the correct product!

Initial delivery was fast as expected. One item was on back order but it's a specialty part and I partly expected it. About the same turnaround direct from manufacturers or elsewhere. The big plus is that the product selection was easy and I found exactly what I needed in less than 10 minutes.

These bushings replace the normal DU bushings in a rear shock. The bushings can be installed by hand (albeit with a lot of force). The reducer seemed to be a bit smaller than it should be and I needed to ream the reducer to fit the 8mm hardware for the bike. I have been using the bushings for a few weeks now and some seriously hard riding. The system works well. Very good shock response and silent operation.

JensonUSA is the best. I've always had great customer service and helpful information from them, shipping is fast and reasonable, and they almost always have the product I need in stock when I need it.

little work to install for retrofit (old aluminum bushings)there is a reducer bushing in the shock that needs to come out. if u do not have the tool to pull bushings a 10mm and 17mmish socket and a good bench vice can press it out.

If u were going to just use aluminum it is a good idea to press it out to replace bushing reducer anyway, so might as well go new style so never have to do again.

old style I had to grease every 10 rides, new no grease! pretty much maint free. way more surface area, when it does eventually wear down, next one will be a snap to install, a big improvement.

Was noticing a small amount of play in my rear triangle when I lifted the bike from the seat. I was concerned that I had egged out the aluminum inserts on the frame. I knew that these were the latest generation bushing for the shock so I installed them and was very pleased that the bike is nice and tight again. Make sure you measure the width on both sides of your shock (shaft end and body end) because mine were different on my Yeti.

Does what it suppose to. Was packaged with everything needed to get my fox shock mounted to my process 134. Be aware that you may need 2 kits for each side of the shock. Mine only needed 1 kit. I would call Fox and see if they have a part number or dimensions for you.

I actually bought these for a rock shox. I’m hoping they are more resilient to the side loads than the original ones. I had to push the DU bushing out other than that they fit like there are supposed to be there. Three good rides. So far so good.

Had an old Fox shock that was creaking. Ended up pressing out the old DU bushing with the Rockshox tool and replacing it with this one. It's nice because it won't require a special tool to replace when the time comes.

Definitely an improvement in design. These bushings are easy to install once the original reducer bushings are pressed out of the shock eyelets. I had play in my shock mount due to wear partly resulting from the original design so I had to order a kit .010" oversize from my frame spec. Once I slipped the slightly larger bushing in my play disappeared. If you have a vice and a bearing press kit you should have no trouble with help from the fox website to switch to this new reducer system.

BEST ANSWER:You need to measure the diameter of the bolt, usually 6 mm or 8 mm, and the length of the old bushing or the space that it fits in. The "hole" (actually a bushing) in the shock is the same for all Fox bike shocks.
